I have acquired a Teac LPU190 record player/radio/USB/amplifier thingy with an annoying digital display.
It won't start. If you leave it off for about an hour, when you apply power the screen lights and then goes dark again. The standby LED is lighted but pressing "standby" does nothing. If you then try again, it doesn't even light the screen.
I thought it was that it needed the clock set, but pressing "mode" for a while also does nothing,
I got it work a couple of times by pressing a combination of buttons but I can't remember what they were. As long as it was plugged in, or re-plugged in within a short period of time it would work.

It seems to use an IC from a clock radio/TeasMaid thing but they haven't connected all the pins. It has a clock but no alarm or sleep mode. You have to press and hold "mode" to view the clock like an old Sinclair digital watch.
It doesn't have flash memory, just a capacitor or CMOS latch or something. Once its "forgotten" the time it goes back to not working.
It seems like the IC is going into "sleep" mode and turning off when you switch it on. I had another thing that kept doing that but I can't remember how I got it to work.
